JLCIC Liangshan School - Intelligent Vehicle - Design Learning

 
Project Description:
This project is a learning and replication project based on the materials provided with the JLCSC Liangshanpai development board. It replicates the entire process of designing, soldering, and programming an intelligent car. This was a learning experience from scratch. Previously, I had never studied embedded systems before. Although I had taken related courses, I lacked a clear goal and hands-on experience. After completing the course, I didn't know what it was for and quickly forgot it. By chance, I discovered that the JLCSC Liangshanpai development board was available for application. I was very interested in the intelligent four-wheel drive car, which had abundant learning materials and video tutorials. So, I applied for a development board, purchased the relevant components, and after a long period of learning, finally built the car. Seeing my own project successfully running was incredibly rewarding. Many problems were encountered during the design process. This article is a simple record of the process from applying for and purchasing the development board to the completion of the car.
1. Development Board Application:
JLCPCB offers free application for the Liangshanpai development board for students. However, to avoid free access and wasted time, a "pay first, receive coupon later" rule is used. You pay for the development board upfront, and within five months, after learning with the board and designing your own project, the money will be refunded in the form of a coupon. The
purchase link is below. Click "Student Free Application," fill in the relevant information, pay, and then wait for the development board to arrive.

2. PCB and Components:
Compared to simple learning, I prefer learning by combining hands-on experience. In the Liangshanpai development board materials, I was interested in the intelligent car section, so I first purchased the related components. To manufacture the smart car shown in the image below, you need to purchase a PCB and components. The PCB, the blue board, is a composite board that connects various components together. It contains copper wires and here also acts as the car's body. Components include resistors, capacitors, LEDs, etc., which can be designed to achieve different functions. You can design these yourself, but my goal was to understand the entire embedded development process, so I used a pre-designed project from JLCPCB.

After opening the link, you will see the schematic and PCB board shown below. Click "Open in Editor" in the lower right corner to open it using JLCPCB's online EDA.
There are several versions available; I chose the second one. There are order options above the project; click to order the PCB and components respectively. Detailed tutorials are available online, so I won't go into detail.
Important Notes: There are a few points to note. PCB printing starts at 5 units, which provides error tolerance but also increases costs. Given the large size of this smart car board, the cost might be 70-80 yuan. Many problems arose during component procurement, especially after soldering, forcing production to stop midway. Components were purchased online. You can buy them from LCSC's online store, or from [other online retailers].
